Appendix A: Data fields

Person name fields may be repeated to accommodate more than one value. If possible, the source of the name must be accounted for, either once for the entire table or as a field within the table. If a legal name is collected, it must be captured according to Table 1, and the collection of an alternate name must also be offered.

Table 1: Required primary and secondary person name fields
Field name Description
Primary name May be the surname, family name, last name, maiden name or married name, main name, mononym (that is, a name consisting of only one word) and in some cases, the entire name where the holder’s name cannot be divided into two parts.
Secondary name The portion of a person’s name that is not the primary name. All remaining portions of the name would be entered into this field.
Name type A metadata field to describe a person name for classifying it for legal, administrative or other purposes (for example, legal name, mononym).
Name source Where the name comes from (for example, an evidence of identity (EOI) document, a court-issued document or an attestation by the person). Primary and secondary names should come from the same source.
Source date The date of issuance of an EOI document or other name source.
Name collection date The date the person name is captured in the dataset.
Last modified date The most recent date any person name field was updated or changed.
Table 2: Alternate person name fields (required if applicable)
Field name Description
Alternate primary name An alternate surname, chosen name, preferred name or alias name of a client.
Alternate secondary name Alternate given name or names of a client that can be used to identify which names in the secondary name field should be used for correspondence (for example, a chosen or preferred name or alias).
Alternate name type A metadata field to describe an alternate name for classifying it for legal, administrative or other purposes (for example, a chosen or preferred name, alias or mononym).
Alternate name source Where the name comes from (for example, an EOI document, a court-issued document or an attestation by the person). For each alternate name, the alternate primary and alternate secondary names should come from the same source.
Alternate source date The date of issuance of a document or other name source.
Alternate name collection date The date the name is captured in the dataset.
